What is the maximum lenght for coaxial cable?Depends on the data rate.The higher the bandwith, the shorter the lenght will be. For exampleanalog standard definition television will run 1000Ft on a good quality, but HD video is limitedto 300feet.

RG6 Coax with Bare Copper versus Coax with Copper Cover AluminiumUtilizing an RG-6 CCTV coaxial cable with a copper covered aluminum braid does not result in compromised electrical performance when compared to an RG-6 CCTV cable with a bare copper braided shield. Insertion Loss, Return Loss and Characteristic Impedance performance all meet the industry standard requirements.

The only difference between the copper clad aluminum braided product and the bare copper braided product is the shield DC Resistance. As a result, the recommended typical run length for the CCA shielded cable is up to 600 ft. versus 750 ft. for a copper RG-6 coax.
